Background technique

With the increasing attention of radon, the state has successively promulgated a series of specifications, requiring the control of hydrogen concentration in various places. The radiation emitted by indoor radon is far greater than the sum of the hazards of other radioactive gases that people encounter. Radon is a gaseous substance, and its attenuator is a non-volatile radioactive substance. Once inhaled into the human body, it will cause damage to the human body and increase the possibility of inducing lung cancer. After inhaled radon gas decays, some dissolve. Because the fluid enters the cell tissue, it causes damage to the cell tissue and eventually induces liver cancer. Therefore, the measurement of indoor radon gas content in the home is of great significance for prevention and control. Using the portable radon gas measuring instrument, we can actively prevent and control indoor radon gas pollution.
